Hi,

I am trying to using headless Chimera on RedHat linux server 7.3 to produce some images. 
But I end up with a segmentation fault. Does anyone have an idea how it comes to this?
The headless chimera is from https://www.cgl.ucsf.edu/chimera/download.html (64-bit daily build).
The test code was taken without changes from https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/basicPrimer.html.
Any ideas will be appreciated.

Best, 
Zhe

PS: OSMesa 11.2.2 has been installed.

Calculation of some surface components failed.


A single component of the surface was calculated correctly - the failure occurred for disconnected  additional components such as inside bubbles.  If the desired surface is already shown, there is no need for concern.  However, if it is not shown, see below for possible fixes.


Surface calculation frequently fails for large, multi-chain structures. The calculation may be successful if the chains are treated individually, by using the "split" command before generating a surface.  If splitting is not desired or the structure is already a single chain, changing molecular surface parameters in the Selection Inspector or (before surface creation) the New Surfaces category of Preferences may allow the calculation to succeed.
